Certified GKH Gardening Expert
Because of the wide variation on weather conditions in California, I do not feel comfortable giving blanket advice on this. But I do know your local extension service will be able to advise you on conditions best for your specific area. Here is a list of the extensions in California (http://ucanr.org/County_Offices/). Select your county and contact them. They will be very happy to help you with growing in your specific area.
